IMPROVEMENT ,IN SAGGER-PlN MACHINES.

i Spectication forming part of Letters Patent No. IS5,S2S, dated January2, 1877; application filed November 25, 1876.

To alt-whom 'it may concern Be it known that l, ISAAC W. KNOWLES, ofEast Liverpool, Columbiana county, in the State of Ohio, lave invented anew ad useful Machine for Forni'ng Sagger or Placing 77 Pins for PlacingEarthenware thereon, which improvement is fully set forth in the'following speciiication, reference being'had to the ac` compauyingdrawing. Q

The object of my invention is to rapidly form sagger-pins by cuttingthem, in place of molding or stamping them, as has been done heretofore.

This I accomplish by the combination, in a sagger-pin machine, of theadjustable claybar guidesA A, feed-bar B,.and head B', having thefriction-roller O, and adjustable toothed plate D, rockshaft kE, andlevers or arms F F', connecting-rod Gr, upright or standard H,crank-shaft 1, pitman K, slide-head L, knives M and N, (N beingadjustable,) knife-guide and resisting-plate O, cranks P, e, and X,pulley R, loose on shaft I, clutch S, all attached or mounted onbed-plate T, as shown in front view, Figure l of the drawing, andfurther .illustrated in plan View, Fig. 2, and end. view, Fig. 3, Figj4being a perspective view of one of the sagger-pins as formed by themachine.

The clay-bar guides A A are attached to the bed-plate T by the screws aa a a, which pass through the slots in the projecting lugs b b b b, sothat the guides can be adjusted to the width of the bar, the spacebetween the guides forming' a trough, in which the clay bar from whichthe pins are cnt slides. tops of the guides A A are level, and form ways, on which the weighted head B' of the feed-bar travels on the rollerG. This roller has only a slight rota-ry motion, and by this motionelevates or dep'esses the teeth of the plate D. This plate has alongitudinal slot in the center, and is attached to the roller C by asetscrew, o, through the slot, so that the plate can be adjusted to thethickness of the i clay bar, the end having the teeth projecting downbetween the guides A A, and the upper end passing through the yoke d,which limits the motion of it and the roller 0.

The rock-shaft E is mounted in suitable bearings behind the guides A Aat the front end. The lever or arm F extends down to and The pivots to.the outer or rear end of the feed-bar B. From the other end of therock-shaft E projects at right angle (upward) the arn or lever F'. Thisarni is longitudinally slotted,

and to it is connected the connectingrod Gr with two sets ofpillow-blocks, which carry i the crank -shaft I. On the rear end ot'this shaft is the crank e, to which connecting-rod G pivots and receivesmotion. About midway from vend to end ofthe shaft is another crank, X,formed in the shaft, to which the pitman K connects, and extends to theslide-head L, Which moves up and down on suitable guides on the face ofthe standard H. The slidehead L is of the shape shown in Figs. l and 2,having a projeotion,f, from the lower portion 'of its face, which givesattachment at the front to the V-shaped knife M. Directly back of thisknife the projection is cut by a perpendicular longitudinal slot,through which a setscrew passes to connect the block U, which carriesthe flat knife N, which, by this arrangemeut, can be adjusted to cut thepins to the desired length. 0 is a compound plate, which rests on thefront end of the guides A A, which are cut away to receive it. The lowerpart is halved out one -third of the width on each side, and one-half inthickness, and has longitudinal slots cut through each ot' the sides.The upper portion ot' the plate has a V-slaped projection at the front,which fits into and guides the V-shaped knife M. Back of this it is cutout in the center, that the center portion of the lower plate can slideinto it when the knife N is moved forward to cut a short pin. The upperplate is also cut down in thickness, so that when the two are slidtogether the center portion of the upper is flush with the sides of thelower. Tlis compound plate 0 has for its object, first, to guide theknives M and N, and, second, to resist or hold the clay bar down, andprevent any spalling of the edges when the knives are withdrawn fromcutting or shaping a pin. The set-screws h h h h hold the plateO inplace. P is a handcrank for giving motion to the machine when operatedby hand. R is a pulley, by which it is operated by power when desired, Sbeing a lever-clutch, by which the pulley is thrown in or out of gear onthe slaft I.

It will be nderstood that crank e is placed on the shaft I with suchrelation to crank X that when the knives are descending and cutting apin the feed-bar B is moving back, and when the feed is moving the claybar up the knives are up and out of the clay.

Operation: The clay from which the pins are to be cut is first squeezedinto lengths by forcing through a dod or die in a square box or tube tothe width and thickness required for the pins. The guides A A are thenadjusted to the width, and the knives M and N and the guide-plate 0 tothe thickness, and also set to the length, ol the pin, the feed beingalso adjusted to the pin-length by moving the connecting-rod pivot G' upor down in the slotted arm F'. The clay bar or length is then pushed inbetween the guides A A, the knives M and N being up until the front endis under M, when the machine isset in motion, cutting one end of the pinsharp by the knife M, while knife N cuts it off the desired length. Thefeed-bar, retreating at the same time, starts to advance the instant theknives withdraw from the clay, which is held down by the plate O. Theroller C, by its friction on the guides A A, turn the teeth of plate Ddown, so as to bite on the clay bar, and move it forward under knives Mand N, the pin last cut being pushed out of the machine by eachfollowing one.

Having thus described my invention and its operation, what I claimis- 1. A machine having one or more knives for cutting and shapi-ngsagger pins from a clay length or its equivalent, for the object setforth.

2. A sagger-pin, when cut from a clay length, in manner as described.

3. The feed-bar B, having the head B', roller C, plate D, and yoke d,all combined and operating as described, for the object set forth.

4. In a sagger-pin machine, the guides A A, in combination with one ormore knives, as described, and for the object set forth.

5. In a saggerpin machine, the compound knife-guide and resisting-plateO, as described, and in combination with knives M and N, for the objectspecified.

6. The combination of the elements A A, B, O, D, E, F F', G, H, I, K, L,M, N, 0, P, R, S, T, U, X, e, and G', all constructed and op.- eratingas described, and for the object set forth.
